Title: Resolution of (cis-1,2-epoxypropyl)phosphonic acid into its optically-active forms
Inventor: CHRISTENSEN BURTON GRANT
IPC: C07F9/6571
Filed: 1968-10-24
Abstract: 1,239,989. Diastereoisomeric salts of antipodes of (cis - 1,2 - epoxypropyl)phosphonic acid. MERCK & CO. Inc. 24 Oct., 1968 [30 Oct., 1967; 15 May, 1968; 20 Aug., 1968], No. 50638/68. Heading C2C. A diastereoisomeric salt of an antipode of (cis - 1,2 - epoxypropyl)phosphonic acid is obtained by reacting a mixture of such antipodes or a salt thereof with an optically active salt-forming compound, and separating and recovering the said diastereoisomeric salt. The optically active salt-forming compound is preferably an optically active base and may be used in an amount sufficient to form the optically active salts of one or both ( + ) and (-) enantiomers. When the salt of one enantiomer is formed the other enantiomer can be recovered from the mixture remaining after separation of the diastereoisomeric salt and when both salts are formed, one of the salts is first separated and the other salt is then recovered. The diastereoisomeric salts formed may be converted to the free (cis - 1,2 - epoxypropyl) phosphonic acid or to a different salt thereof, e.g. to an alkali metal- or alkaline earth metal salt. The process can also be carried out by reacting a mixture of the enantiomers with a mixture of an optically active base and an optically inactive salt-forming base and separating the optically active base salt of one of the enantiomers from the resulting reaction mixture, at least one-half mole of the optically active base being preferably used per mole of the enantiomers. In this procedure the two bases may be added to a solution of a mixture of the antipodes in a solvent and the optically active salt of one of the enantiomers separated from the reaction mixture. Thus the (+) - α - phenethyl - ammonium (-)(cis - 1,2 - epoxypropyl)phosphonate crystallizes from an aqueous solution of a mixture of (+) - α - phenethylamine and triethylamine salts of the racemic phosphonic salt. The optically active bases may be for example amines, hydrazines, imines, imino-esters, hydrazides, phosphines, biphosphines, phosphonium, stibonium or sulphonium compounds, stibines, arsines, alkaloids (e.g. (-) quinine), amino steroids or amino acids and several suitable bases are specified. Optically active allenes, spiranes, biphenyls, cycloalkenes and certain substituted ethanes may also be used as saltforming compounds. The diastereoisomeric salts can be separated by fractional crystallization from suitable solvents, especially C 1 -C 5  alkanols or aqueous C 1 -C 5  alkanols, or by chromatography or by the use of ureas, thioureas, or clathrates to form inclusion products with one of the diastereoisomeric salts.
Patent GB-506951-A (GB)
Abstract: 506,951. Electric control systems. LANDIS & GYR AKT.-GES. April 12, 1938, No. 11207. Convention date, June 21, 1937. [Class 40 (i)] In a remote control system of the type employing synchronous distributers, a desired operation at the receiver is effected by one or more primary relays operated by tuned impulses and adapted to switch in a secondary control relay which responds to a further impulse. When an impulse is received by the relay 4, a motor 9 is started up over a circuit 3, 2, 5 and the distributer arm 2 is driven over its contacts. When the arm 2 leaves contact 5, contacts 6, 7 are operated by the selector to maintain closed the circuit of the motor. The Figure shows only the primary and secondary relays 12, 17 for controlling a single circuit 22, but further circuits may be controlled by relays connected to other contacts of the distributer. When the arm 2 engages contact 10, the receipt of another impulse operates relay 12 which prepares relay 17 for operation over the contact 13 or 14 in response to a further impulse. Shortly before the arm 'arrives in its initial position, contact 19 is operated to restore relay 12 to normal and when the arm engages contact 5 the contacts 6, 7 are restored to open the motor circuit. Contacts 18 intermediate the selector contacts 10, 13, 14 are provided to effect restoration of relay 12 and thereby prevent operation of relay 17 in the event that the impulse received when the arm 2 co-operates with contact 10 is prolonged. In a modification, the two-winding relay 12 is replaced by a single winding relay provided with a locking circuit which is short-circuited to effect restoration. In the latter arrangement, the contact 19 may be included in the locking. circuit. In another arrangement, several primary relays 12 are arranged for operation in succession to prepare the circuit of the control relay 17.

Filed: 1971-11-02
Abstract: 1364097 Mixing apparatus C ZOPPELLARI and F NOVELLI 2 Nov 1971 [6 Nov 1970] 50820/71 Heading B1C [Also in Division F4]  A machine for the continuous manufacture of soft ice-cream comprises a cylindrical refrigerated chamber 8, a reservoir 4 having a conduit 5 connecting the reservoir to the chamber 8, a first rotary body which includes a set of blades 27, and a second rotary body 20 in the form of a helically grooved screw. A grooved pulley 13 driven by a motor is used to rotate the rotary members, such that the drive ratio between coaxial shafts 19 and 23 is such that the angular speed of the working body consisting of the blades 27, 29 will be greater than the angular speed of the screw  20. The temperature inside the chamber 8 diminishes from right-to-left as viewed in Fig. 2. In operation, a charge of a liquid ice-cream mix contained in the reservoir 4 flows along duct 5 to duct 7 when a top 31 is opened by a handle 32. The liquid is then mixed with air from pipe 33 to a correct consistency, and passes to the refrigerated cylindrical passage 8. In the passage 8, it is whipped and aerated by the rotation of the blades 27 and 29. The surfaces of blades 27 contain recesses and of blades 29 apertures. The mixture is then drawn by the screw 20 along the chamber along the surface of the chamber 8 to the outlet 22. The machine may be stripped down for cleaning purposes, by a hand wheel 34 being moved sideways allowing the block 26 to be disengaged. The block can then be slid along guides 35. Alternatively, a detergent solution may be placed in the reservoir 4, and churned through the machine.

Title: Brake delay valve
IPC: B60T15/36
Filed: 1974-11-27
Abstract: 1491046 Fluid pressure brakes CATERPILLAR TRACTOR CO 27 Nov 1974 [3 Dec 1973] 51423/74 Heading F2F In a braking system for a vehicle of the type having a bucket or other implement manipulated by means of hydraulic power, the braking pressure can be relatively rapidly increased as fluid pressure is increased and initially rapidly released to a predetermined level and then less rapidly released. As shown a  brake delay valve 10 is associated with a system 12 for automatically neutralizing a vehicle transmission upon application of the brakes. The system 12 includes a pump 14 and accumulator 30 supplying hydraulic fluid to brake control valves 16, 18 operated by left and right pedals 32, 34. Operation of the right pedal 34 directs fluid to the vehicle service brakes 36 through a double check valve 40 while actuation of the left pedal 32 directs fluid pressure to valve 10 and to a transmission neutralizing valve 50 which is normally spring biased to the "off" position, the valve 50 when actuated dumping fluid pressure from a pump 54 which supplies the transmission control 52. The valve 10 (Fig. 2) has a body 56 with progressively larger concentrically stepped bores 58, 60, 62. Fluid enters the valve through an inlet port 68 and is discharged from an outlet port 72 and between the ports is communicated to passages 74, 76, 78, a check valve 80 being disposed in passage 74 between port 68 and bore 58 and a check valve (not shown) being disposed in passage 78 to prevent the return of fluid therethrough. A fourth passage 86 communicates fluid pressure at the outlet port 72 to bore 62. A valve spool 88 has lands 90, 92, 94 and a reduced diameter portion 100 prevents land 90 from blocking passage 74 and permits pressure therein to be exerted on the end face 102 of the spool. A piston 106 is slidable in bore 62 against a spring 110 seating on a shoulder 112 between bores 58, 60, a smaller diameter spring 114 urging the piston 106 and spool 88 apart. Operation of pedal 32 causes fluid to flow through passages 74, 76, 78 and the fluid pressure also is communicated to the end face 118 of piston 106 and end face 102 of spool 88 via passages 86, 74 respectively. When piston 106 is bottomed in its bore an accumulator chamber is defined in bore 62 between a plug 66 and the piston. Upon release of pressure to valves 10, 50 the transmission begins re-engagement and the volume of fluid in chamber 120 is slowly metered through an orifice 82 as spool 88 moves and after the desired time delay communication is re-established through passage 76 via an annular recess 98 of the spool. This quickly releases the remaining holding pressure.
